Description

Technical Field

[0001] The present invention relates to the field of file management technology, and in particular to a method for editing and managing nuclear facility decommissioning simulation files based on cloud and local collaboration. Background Art

[0002] In the processing of nuclear facility decommissioning simulation files, there are currently many significant problems, which directly affect the work efficiency, data security and operational coordination of nuclear facility decommissioning. First of all, data consistency is a key challenge. Since nuclear facility decommissioning simulation involves the participation of multiple users and teams, modifications made by different users on files can easily cause version conflicts and data inconsistencies. For example, when multiple users modify the same file at the same time, the inability to effectively detect and handle conflicts will lead to inconsistent content between different versions of the file. This not only seriously affects the accuracy and consistency of the work, but also increases the complexity of subsequent work, because the team needs to spend a lot of time manually resolving these conflicts. In addition, this data inconsistency will also lead to deviations in subsequent analysis results, which will directly affect the scientificity and safety of the decommissioning plan.

[0003] Secondly, the difficulty in collaborative editing of multi-format simulation files is also a major bottleneck. In the process of nuclear facility decommissioning simulation, multiple data file types are often involved, such as three-dimensional model files (such as CAD format) and professional physical simulation data files. The formats of these files are different and the compatibility is poor, which makes it difficult to achieve unified file operations and editing during collaborative work. For example, when multiple users process files in different formats, additional format conversion tools are usually required to ensure that different files can be processed in the same system. This not only increases the complexity of the operation, but also prolongs the working time and reduces the efficiency of the entire collaborative work, which may delay the overall progress of the decommissioning process.

[0004] In terms of security and authority management, security vulnerabilities are common in nuclear facility simulation file processing systems, especially the risk of unauthorized access and data leakage. The sensitivity of nuclear facilities determines that simulation data must be strictly protected. Once these data are leaked or unauthorized accessed, it will not only threaten the safety of nuclear facilities, but also cause major information confidentiality risks. At present, the authority control function of many simulation file management systems is not perfect, and it is impossible to implement refined authority management according to user roles, which easily leads to files and data being accessed and operated by unauthorized personnel. In addition, many systems lack comprehensive security audit functions, and are unable to detect potential security threats in a timely manner and take effective countermeasures.

[0005] The lack of offline collaboration capabilities is also a major limitation in nuclear facility decommissioning. In actual work, nuclear facility sites often face limited network connectivity, and existing simulation file management systems rely on a stable network environment for collaboration. When the network is limited, collaborative work cannot proceed smoothly, limiting the scope and flexibility of work, especially the collection and analysis of field data. In addition, since offline operations cannot be achieved, it is difficult for personnel to effectively perform decommissioning simulation tasks in an unstable network environment.

[0006] Finally, the inefficiency of data backup and recovery mechanisms makes recovery very difficult in the event of data loss or erroneous operation. The backup mechanism of existing systems often relies on regular manual backups and cannot cope with the needs of real-time data loss. When erroneous operations or system failures occur, the lack of effective recovery methods can easily lead to permanent loss of important data, seriously affecting the smooth progress of decommissioning work. Summary of the invention

[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the art without creative work should fall within the scope of protection of the present invention.

[0027] Example 1, reference Figure 1-Figure 4 , is an embodiment of the present invention, and provides a method for editing and managing nuclear facility decommissioning simulation files based on cloud and local collaboration, including:

[0028] S101: Verify user identity, receive files and convert file formats.

[0029] Furthermore, verifying the user's identity includes the user authenticating through the system client or web interface, entering a username and password to start the multi-factor authentication (MFA) process. The system uses a role-based access control (RBAC) model and multi-factor authentication technology to ensure the security and accuracy of the user's identity. After verification, the system assigns fine-grained permissions based on the user's role attributes. Entering a username and password to start the multi-factor authentication (MFA) process. The system uses a role-based access control (RBAC) model and multi-factor authentication technology to ensure the security and accuracy of the user's identity

[0030] It should be noted that when receiving files, including when users select nuclear facility decommissioning simulation files to upload, the system performs end-to-end security checks, including but not limited to virus scanning and malware detection, to ensure the security of uploaded files. The system also uses content filtering and sandbox technology to isolate and analyze uploaded files to prevent potential security threats.

[0031] In the embodiment of the present application, for common formats (such as 3D model files in CAD format, professional data analysis file formats, text format files, image format files, etc.), files are converted to a unified intermediate format for storage and processing when uploaded, retaining key information and structure and normalizing data. Convert back to the original or specified format when downloading or viewing. Provide corresponding editing interfaces and tools for files in different formats during collaborative editing. The format conversion plug-in mechanism is used to facilitate subsequent support for new formats, achieve seamless compatibility and collaborative processing, and improve team collaboration efficiency and flexibility.

[0032] The specific operation is that the files that pass the security check enter the format parsing stage, and the multi-format simulation file compatibility engine in the system uses professional file parsers, such as the OpenCASCADE library, to extract graphic elements and parameter information. Subsequently, the files are converted into a unified intermediate format within the system, such as an XML-based markup language, to normalize and standardize the data, ensuring that files of different formats can be uniformly managed and processed in the system.

[0033] S102: Process the simulation file through the first collaborative editing and perform real-time audit.

[0034] Furthermore, when the user opens the simulation file in the system interface for editing, the system uses cloud computing technology to quickly read the file data from the distributed storage and display it to the user. It supports multi-user real-time editing, which is based on the first collaborative editing.

[0035] It should be noted that the first collaborative editing may be a real-time collaborative editing system based on optimistic concurrency control (OCC) and WebSocket, or a real-time collaborative editing system based on a locking mechanism and long polling, or other suitable collaborative editing systems.

[0036] In the embodiment of the present application, the first collaborative editing is a real-time collaborative editing system based on optimistic concurrency control (OCC) and WebSocket. The optimistic concurrency control (OCC) and WebSocket parts provide operations to users respectively, such as Figure 3 As shown in the figure, optimistic concurrency control (OCC) assigns a version number to each user operation, compares the operation version numbers when submitting, detects and resolves conflicts. WebSocket transmits user operations in real time through two-way communication, allowing the server to synchronize and process user editing requests in a timely manner. When multiple users edit the same area, the system determines conflicts through version number comparison and location detection, and prompts users to manually resolve conflicts when necessary. For example, if two users make different modifications to the content of the same area and the version numbers are inconsistent, a conflict is determined. The conflict resolution adopts a merge strategy, which can prompt users to manually resolve it. The conflict content and location are displayed through a visual interface, and users can choose to keep, accept, or manually merge the changes.

[0037] Specifically, the server-side Conflict Detection and Resolution Intelligent Algorithm (CDRIA) handles concurrent operations, assigns a version number to each operation through optimistic concurrency control (OCC) technology, and detects and resolves conflicts.

[0038] In another optional embodiment, the first collaborative editing is a real-time collaborative editing system based on a locking mechanism and long polling. The system first locks the file. When the user edits the file, the system locks the area edited by the user, and other users cannot operate in the locked area. This can avoid direct operation conflicts and ensure that no editing conflicts occur between users. The client periodically sends requests to the server to obtain the latest updates of the file. If the file is modified, the server will respond immediately and return the latest file data. Otherwise, the connection is maintained until there is a new update. Through the locking mechanism of the file area, multiple users are actively prevented from editing the same area at the same time to prevent conflicts.

[0039] Both methods can achieve consistency in real-time editing by multiple people. The client sends the operation information to the server in real time through WebSocket or long polling. After receiving the information, the server uses the message queue to process it, updates the file through distributed transaction processing, and then pushes the updated content to other user clients through SSE real-time data push technology. In order to achieve millisecond-level response speed, data transmission uses GZIP compression algorithm to reduce transmission volume, optimize network transmission protocol, and use Redis cache technology to reduce repeated transmission and reading time to ensure real-time consistency.

[0040] It should also be noted that in order to support the response speed when multiple users operate simultaneously, the present invention adopts the method of cloud computing and distributed storage, and through virtualization technology, tasks are assigned to multiple virtual servers to realize flexible resource scheduling and elastic expansion. For example, using distributed file systems (such as Ceph, GlusterFS, etc.), using data sharding and redundant storage strategies, file data is dispersed and stored in multiple nodes to improve data reliability and read-write performance. The data copy mechanism ensures that data can be automatically restored when a node fails, and load balancing technology (such as LVS, Nginx, etc.) optimizes user request allocation, improves overall system performance and response speed. At the same time, the use of erasure code technology further optimizes storage space and data reliability, reduces storage costs and improves fault tolerance.

[0041] Furthermore, in order to support users to save files at any time during the editing process, the system uses a version control algorithm (VCA) to calculate and store the differential information of file versions. Each version is assigned a unique version number and records detailed metadata information, such as creation time, author, and modification instructions. The system provides version management functions, allowing users to view historical versions, compare version differences, and roll back to any historical version as needed, and use file comparison algorithms such as patdiff to generate difference reports.

[0042] The version number is generated using a UUID generation algorithm (such as Version 1 or Version 4) to generate a unique identifier for the file and its version. A UUID is assigned when the file is created and the associated related information is stored in the database. A new UUID is generated for each modification and version update, and a version chain relationship is established to record the UUID and previous and next version information. The B+ tree index technology is used to quickly locate file versions and historical change records to ensure data consistency and traceability.

[0043] It should be noted that the system conducts security audits on all user operations, recording information such as user login time, IP address, and operation content. These audit logs can be used for subsequent security tracing and problem troubleshooting. If abnormal operations or security incidents are found, the system administrator can analyze the audit logs through the Security Information and Event Management (SIEM) system and take timely measures to prevent and respond.

[0044] S103: Setting file operation permissions based on the first encrypted storage file.

[0045] Furthermore, for sensitive nuclear facility decommissioning simulation file data, the system uses first encryption during storage and transmission.

[0046] In the embodiment of the present application, the first encryption uses the TLS protocol and the distributed redundant storage encryption method. During the data transmission process, the TLS protocol is used to encrypt the transmitted data to ensure the confidentiality and integrity of the data during network transmission. The file data is stored on multiple nodes, and the redundancy mechanism is used to ensure that the data can still be recovered even if some nodes fail. Specifically, during data transmission, the transport layer security (TLS) protocol is used to encrypt the file, and the data is stored after the encryption is completed, and the data is distributed and stored in each node through a distributed storage system.

[0047] In an optional embodiment, the first encryption uses an end-to-end layered cold storage encryption method, in which the encryption operation is initiated from the user end. The file is encrypted before being uploaded to the server, and only authorized users can decrypt the file. Even if the server is hacked or the data is leaked, unauthorized third parties cannot read the encrypted file. The file data is stored in a cold storage system with low frequency of access. The cold storage layer will enhance data protection and reduce the attack surface through offline backup, tapes, etc.

[0048] It should be noted that after the user completes editing, he or she can choose to download the file to the local computer. The system will convert the file in the internal unified format back to the original format or other specified format, such as STEP or IGES format, according to the user's needs for the user to use. This step ensures the compatibility and availability of the file, making it convenient for users to use the file in different environments and platforms.

[0049] If users need to share files with other team members or related personnel, they can do so through the sharing function provided by the system. The system will control other users' access rights to shared files based on the user's permissions and sharing settings. For example, users can set certain files to be viewed and edited only by a specific user group, or to be read-only. During the sharing process, data security and consistency are still guaranteed, and real-time data synchronization and version control ensure that all users see the latest and correct file versions.

[0050] Example 2, an embodiment of the present invention, provides a nuclear facility decommissioning simulation file editing and management method based on cloud and local collaboration. In order to verify the beneficial effects of the present invention, scientific demonstration is carried out through economic benefit calculation and simulation experiments.

[0051] First, this embodiment provides a nuclear facility decommissioning simulation file editing and management system based on cloud and local collaboration to verify its performance in multi-user collaborative editing, efficient storage and data security. First, the experiment simulated a scenario of a nuclear facility decommissioning project, in which multiple users edited simulation files at the same time, and the file formats included CAD three-dimensional models, professional physical analysis data files, and text format files. The experimental objects included 20 different types of simulation files, and the file sizes ranged from 10MB to 500MB.

[0052] Table 1 Experimental data comparison table

[0053]

[0054] It can be seen from the above table data that the nuclear facility decommissioning simulation file editing and management system provided by the present invention has shown significant advantages in various parameters. First of all, in terms of file upload and download time, since the system adopts distributed storage and load balancing technology, the file upload and download speed is significantly faster than the traditional system. For example, for a 500MB simulation file, the upload time is 45.2 seconds and the download time is 40.1 seconds, which is significantly more efficient than the 60 seconds or more in the prior art. This advantage comes from the efficient data sharding and parallel processing capabilities of the distributed storage system.

[0055] In terms of collaborative editing conflict handling, the present invention uses technology based on OCC and WebSocket to significantly shorten the conflict handling time. For example, the conflict handling time of simulation file 6 (500MB) is only 2.4 seconds, while the traditional locking mechanism takes more than 5 seconds. Such an improvement shows that OCC's version control mechanism can quickly detect and resolve conflicts during multi-user editing, ensuring the continuity and efficiency of the editing process.

[0056] The present invention also has a strong data recovery capability. Experimental data shows that the recovery time of a 500MB file is only 5.1 seconds, thanks to redundant storage and erasure coding technology. Compared with the recovery time of more than 10 seconds required in traditional systems, the present invention can quickly restore the integrity of the file when data is lost, significantly improving the reliability of the data.

[0057] In addition, in terms of encrypted transmission and data integrity verification, the present invention achieves dual guarantees of security and efficiency through the combination of TLS protocol and GZIP compression technology. Experimental data show that even for a 500MB file, the delay of encrypted transmission is controlled within 55 milliseconds, and the data integrity verification time is only 1.3 seconds, which is excellent in similar systems. Traditional systems often have transmission delays of more than 100 milliseconds due to the unoptimized encryption technology, which affects real-time performance.

[0058] Embodiment 3, an embodiment of the present invention provides a nuclear facility decommissioning simulation file editing and management system based on cloud and local collaboration, including a file receiving module, a collaborative editing module, and a storage sharing module.

[0059] The file receiving module is used to verify the user identity, receive the file and convert the file format. The collaborative editing module is used to process the simulation file through the first collaborative editing and perform real-time audit. The storage sharing module is used to set the file operation permission based on the first encrypted storage file.

[0060] If the function is implemented in the form of a software functional unit and sold or used as an independent product, it can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of the present invention, or the part that contributes to the prior art, or the part of the technical solution, can be embodied in the form of a software product.
